Title: Automatic gated potential-control system
IPC: G01S7/12
Filed: 1952-08-20
Abstract: 717,886. Automatic control system of time-base generators. HAZELTINE CORPORATION. Aug. 20. 1952 [Sept. 13, 1951], No. 20910/52. Class 38(4) The datum level of a repetitive sawtooth waveform (the time base of a radar P.P.I. display) is maintained at a predetermined potential by connecting a point in the time base circuit to a potential divider which is automatically controlled in accordance with the error in the datum level. This connection is made during the interval between successive saw-tooth sweeps, the point being isolated during the sweeps. The output of a sweep amplifier 20 is coupled by a condenser 21 to a further amplifier .23. The voltage at point 28, i.e. the voltage between the input of amplifier 23 and earth, is applied to one control grid of a cathodecoupled pair 49, 50 where it is compared with a reference bias applied to the other grid from a potential divider 51. The amplified error signal controls a valve 29 which (assuming that diodes 36, 38 are conducting) forms the adjustable part of the potential divider effectively connected to point 28, the other part being resistors 37, 39 in parallel. This potential divider is connected between a positive H.T. supply and a negative bias supply -B, hence a selected potential (normally zero) can be maintained at point 28 bv varying the conductivity of valve 29. This correction occurs in the intervals between successive sweeps when a negative gating pulse (from a generator 17) causes valves 40, 44, 47 to be cut off.. During each sweep, a positive gating pulse causes all these valves to conduct. Valve 40 conducts through resistors 42, 39, threby raising the cathode voltage of diode 38 so that it blocks. Valve 44 conducts through resistor 46, raising the cathode voltage of valves 4.8, 50 so that they cut off. Valve 47 conducts through resistor 35.to reduce the voltage applied to the grid of valve 29 so that the anode voltage of diode 36 is reduced and it blocks. Hence the point 28 is isolated by the two diodes, and the correction system is blocked until the end of the sweep.

Title: Improvements in and relating to the form of floating vessels
IPC: B63B1/04
Filed: 1932-07-26
Abstract: 398,011. Ships' hulls. ISHERWOOD, SIR J. W., 4, Lloyds Avenue, London. July 26, 1932, No. 21097. [Class 113 (ii).] Mercantile ships have the sides of the middle body portion curved inwards from the loadwater line to the floor line without a sharp turn of bilge. The form is determined by first setting out a rectangle equal to the required midship section area of the ship, the upperhorizontal line A-A of the rectangle corresponding to the required water-line and the base following the bottom of the vessel. The beam of the ship is then increased to any desired extent between 5 and 15 per cent, and the frame-moulding line 2 is carried downwards at first almost vertically and then in a fair inwardly-falling curve until it joins the bottom at not less than one-third of the maximum beam. The midship area thus determined is approximately the same as that of the rectangle. The frame-moulding line intersects the bilge diagonal at not less than 14 per cent of the total length of the latter. A formula for the arc-form is given. The curve may be continued above the water-line upwards or this portion may be made wall-sided. Specification 21177/97, [Class 113, Ships &c., Div. I], is referred to.

Title: Pulse duration modulator
IPC: H03K7/08
Filed: 1971-04-19
Abstract: 1347563 Pulse modulation circuits; monostable circuits ROUSSEL UCLAF 19 April 1971 [10 Feb 1970] 21131/71 Headings H4L and H3T [Also in Division G4] A pulse-width modulator circuit comprises a monostable multivibrator 1, 2 which has transistor 1 cut off by timing pulses at 13, causing 2 to saturate, and then recovers as capacitor 3 charges from constant-current source 18, a modulating signal at 25 controlling the point at which 2 begins to desaturate. In order to accelerate the switching a transistor 28 is provided, acting as a current amplifier, and when 27 starts to conduct to initiate the switching amplifiers 31, 34 become operative to produce a switching pulse at the base of transistor 1. The effect of the voltage of source 15 in causing the pulse width to differ from a strictly proportional relationship to the modulating voltage 25 may be eliminated by providing a second circuit identical to that of Fig. 2, but with earth potential supplied at 25, and supplying the outputs of the two circuits to an anti-coincidence gate. In a modification the current supplied by transistor 18 is controlled so as to be proportional to a second input voltage, the pulse width then being proportional to the ratio of the two inputs. Specification 1,135,624, which describes a pulse width modulating circuit of which the present invention is an improvement, is referred to.
